Updated rxvt-unicode packages fix CVE-2014-3121

Description

Updated rxvt-unicode package fixes security vulnerability:
rxvt-unicode (aka urxvt) before 9.20 is vulnerable to a user-assisted
arbitrary commands execution issue. This can be exploited by the unprocessed
display of certain escape sequences in a crafted text file or program output.
Arbitrary command sequences can be constructed using this, and unintentionally
executed if used in conjunction with various other escape sequences
(CVE-2014-3121).
